With the very real possibility that a close friend may purchase my 911 I am considering a Cummins swap for my truck. I'd like to eventually make 400-500hp at the wheels without spending more than I need to. Which engine would be best? 12v, 24v, common rail? I don't expect to go beyond that level of performance. I need a good dependable daily driver and tow rig. I would likely do a ZF6 conversion at the same time. I like my IDIT but it's not practical for building more power, a PSD swap seems too involved. I do have a line on used Cummins engines from "timed out" Fed Ex trucks. I don't think there are any common rails but there are definitely 12v and 24v's available for a good price. So with those things in mind what do some of you guys with experience recommend?
